Abstract

To develop a reliable and valid measure of short-term quality of life after abdominal surgery. A major limitation of clinical trials evaluating laparoscopic surgical procedures has been the lack of a measure of short-term quality of life after abdominal surgery. We used existing health status measures, focus groups, and semi-structured patient interviews to generate a prototype questionnaire of 51 items, which was administered to patients within 2 weeks after an abdominal surgical procedure. We used structural equations modeling to reduce the number of items, retaining the three items with the highest factor loadings on each of the factors that accounted for one or more eigenvalue. We administered the prototype questionnaire to 500 patients (mean age [SD] 53.4 [16.0], 51.4% male, 73.0% inpatient) at a mean 4.1 days after an abdominal surgical procedure. Item reduction yielded an 18-item measure with 6 sub-scales. The final instrument demonstrated good model fit in relation to our hypothesized factors (root mean square error of approximation 0.085, goodness-of-fit index 0.89). We developed a reliable and valid 18-item, 6-subscale measure of health-related quality of life after abdominal surgery, for use as an outcome measure in ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.

Psychiatric Chronotherapy

Psychiatric Chronotherapy considers the circadian rhythm as a major factor for optimizing therapeutic efficacy of psychiatric interventions. Discover the latest research on Psychiatric Chronotherapy here.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
